Specification of Letters Patent.

Patented oct. 23, 1906.`

. Application filed April 27, 1906. Serial No. 313,931.

. vv'a citizen of the .United States of America, re-

siding at McKees Rocks, in the county of Allegheny and State ofPennsylvania,jhave invented certain new and useful Improvements inWindow-Shade Adjusters, of which the following is a specification,reference being had therein to the accompanying drawings,

This invention relates to certain new` and useful improvements inwindow-fixtures, and the invention relates more particularly to theadjustment of awindow-shade roller in a window-frame.

The primary object of this invention is the provision of novel means foreasily and quickly adjusting a shade-roller in a windowframe, whereby ashade of'less depth than the window-frame can be adjusted to any part ofthe window-frame to shade the light passing through the same. 1

- Another object of this invention is the provision of novelVmeanswhereby a windowshade roller can be easily and quickly mounted in awindow-frame without necessitating the use of a step-ladder or similarelevating object, but permit of the curtain-shade roller beingpositioned at `the upper end of the frame. l'

A further object ofthis invention is the provision of novel means fordetachably supporting a curtain-shade roller in a window-- frame.

A still further object of this invention is to provide a fixture for awindow-frame which will be extremely simple in construction, strong anddurable, and comparativelyinexpensive to manufacture.

With the above and other objects in view, which will more readily appearas the nature of the invention is betterV understood, the same consistsin the novel construction, combination, and arrangement of parts to behereinafter more fully described and claimed, and, referring to thedrawings accompanying this application, like numerals of referencedesignate corresponding parts throughout the several views, in which#Figure 1 is a front elevation of a windowframe equipped with my improvedfixture. Fig. 2 is a vertical sectional view of a pulley or sheave usedin connection with my improved ixture. Fig. 3 is a front elevation of acurtain-shade-roller hanger used in connection with 'the xture. Fig. `4is a vertical sectional view of the same. Fig. 5 is a longitudinalsectional view of another set of pulleys or sheaves vused in'connectionwith the fixture. Fig. 6. is a front elevation of a hanger, illustratinga slight modication of the hanger illustrated in Figs. 3 and 4 of thedrawings. Fig. 7 is-a vertical sectional view of the same. y

In the accompanying drawings'Ihave illustrated a window-frame asconsistingof side rails 1 and 1', a sill 2, and a top rail or lintel 3,the window-frame having two sashes 4 and 5 adjustably mounted therein.

My invention resides in providing the window-frame with a fixtureconsisting of two sets of sheaves or pulleys 6 and 7 and single sheavesor pulleys'S and 9, the sheaves or Vpulleys 6 and 7 being secured to theunderneath edge of the top rail 3 at the ends thereof, while the singlesheaves or pulleys S and 9 are secured to the lower inner edges of therails 1-and 1.

The set of sheaves or pulleys 6 comprise a casing 10, having groovedwheels 11 and 12 j ournaled therein, vthe set of pulleys or sheaves 7bein similar to the set described;l

but for the sa re of clearness I have designated the grooved wheelsthereof 14 and 15. The single sheaves or pulleys are identical andcomprise casings 16 16, having grooved wheels 17 and 18 journaledtherein.

An endless cord or cable 19 passes over the vvarious grooved wheels, thecable passing sheave 9, the endless 'cable passing around three edges ofthe window-frame.

In conjunction with the cable 19 I use hangers 2() and 21, these hangersbeing preferably constructed of metal and are identical in constructionwith the exception that the lower end ofone hanger is provided with akeyhole-shaped slot 22, while the lower` end of its associate hanger issimply provided with a circular opening to accommodate the ends of acurtain-shade roller 23. The upper ends ofthe hangers are slotted, 4asat 24 24, and the innermost strands ofthe cable 19 are moved into saidopenings and a pin or late 25 inserted between the cable, 19 an the roo

hangers, thereby fixing the hangers upon the innermost strands ofthecable 19.

In Fig. 6 of the drawings have illustrated a slight modication of thehangers 2O and 21, wherein a plate 26 is employed, the lower end of theplate being slotted, as at 27, to aecommodate one end of thecurtain-shade roller 23, while the opposite endof the plate is providedwith an opening 28. From one side Wall of Ithe slot 28 projects "anintegral arm 29, formed with a head 30. This 'construction permits thecord r19'to ube readily looped o'verlthe headed arm 29, :thus avoiding'the threading of the cord "through 'the slots 24. (Shown in Figs. 3 and4.)

Bysre'ferringto Fig. 1 of the drawings it will be observed that thestrands of thecable 19 at the upper edgeof the windowframe cross oneanother, whereby when'the innermost strand ofthe cable at the righthandside 'ofthe frameis pulled downwardly a similar movement will 'beimparted'to the innermost strand uponthe'lefthand side of the frame,thereby simultaneously lowering the hangers v2O 'and 21 'and moving thecurtain-shade rollers 23 evenly within the wink dow-frame. A downwardpull upon either one ofthe outer strands` ofthe cable 19 will raise thecurtain-shade roller 23, and by the novel arrangement ofthe cable 19 Iam enabled to easily and quickly adjust'the curtain-shade 'roller (toany desired position withinthe window-frame, while thecurtains'hade'oftheroll'er can beraised and lowered independently of thecable 19.

I do not care to confine myself to the type of window-'frame 1nconnection with which my improved window-iixture is used or to `the sizeand minor details of construction, as

such changes as are permissible by the appended claim may be resorted towithout departing from the spirit and scope of the invention.

`What I claim, and desire to secure by Letters Patent, is-

The `combination with the window-frame, ofthe casings 6, 7, attachedtothe frame at the upper corners thereof, a pair of pulleysmountedwithin and inclosed by each of said casings and having their axison different horizontal planes, casings S, 9, attached to the frame atthe lower corners thereof', and a single pulley within and inclosed byeach of said casings 8, 9, a single endless cord passing over thepulleys in casings S, 9, and doubled to form two vertical continuousstrands at each side of the window-frame and passing over each of thepulleys in easings 6, 7, a shade-roller, hangers receiving the pintlesof said shade-roller and threaded onto the inner vertical strands ofsaid endless cord, and a pin carried by the hangers for holding the samein adjusted position on the endless cord.

In testimony whereof I aliix my signature in the presence of twowitnesses.
